Kaiser Aluminum appeals from a jury verdict in favor of plaintiff-appellee Fabri-ca Italiana Lavorazione Materie Organiche, S.A.S. (FILMO) in this diversity action for breach of contract. Kaiser alleges that the trial court erred in striking one of Kaiser’s defenses, in failing to construe the contract as a matter of law, in not directing a verdict for Kaiser, and in excluding the testimony of one of Kaiser’s expert witnesses. Finding no reversible error, we affirm.
I. Background
In September 1979, FILMO and Kaiser Aluminum reached an agreement by telephone for Kaiser to sell FILMO 8,000 metric tons of diammonium phosphate (DAP).
In November, 1979, FILMO nominated a Soviet vessel, the BELOYODSK, to ship the DAP from Tampa. On November 20, FIL-MO requested that Kaiser “accept the stem” of the BELOVODSK (i.e., approve shipment in the named vessel). Kaiser did so in a telex which also stated “Pis keep us advised any change ETA of this vessel as we must repeat must have vessel loaded prior end Dec. 79.” FILMO then found that because of problems in Cuba, the BE-LOVODSK could not arrive in Tampa before December 31, and nominated a substitute Soviet vessel, the UELEN, to accept shipment. The UELEN was expected to arrive in Tampa on December 29. Because a ten-day time lag existed between a ship’s arrival at the Tampa port and berthing for loading, on December 28, Kaiser informed FILMO that the ship could not be loaded prior to the December 31 deadline, and “cancelled” the contract. 2 FILMO immediately purchased “cover” DAP pursuant to U.C.C. §§ 2-711 and 2-712, F.S.A. §§ 672.-711 and 672.712 3 for loading on the UEL-EN, but by the time the UELEN reached the loading berth, the International Longshoreman’s Association had instituted a boycott of Soviet vessels and refused to load the UELEN. FILMO then obtained a non-Soviet vessel to ship the DAP and sued Kaiser for breach of contract.

Kaiser first complains that the trial court committed reversible error by striking its eleventh affirmative defense. This defense related to the ILA boycott of Russian ships which prevented the loading of the UEL-EN. At trial, Kaiser referred to this as an impossibility defense, arguing that it was not liable to FILMO because the boycott prohibited timely performance of Kaiser’s obligations to load the DAP. On appeal Kaiser has reformulated its claim into one of proximate cause. 4 Essentially, Kaiser argues that it is not liable for the damages suffered by FILMO because the ILA boycott prohibited shipment of the DAP on the vessel nominated by FILMO, the UELEN. Kaiser asserts that the boycott caused FIL-MO’s damages, not Kaiser’s prior breach. 5
We conclude that in the context of this case Kaiser’s defense was legally insufficient. U.C.C. § 2-610, F.S.A. § 672.610, states that after a party repudiates the contract, the aggrieved party may suspend his own performance and resort to any remedy for breach. One of these remedies is “cover”: the aggrieved party immediately may purchase substitute goods and recover as damages the difference between the cost of cover and the contract price of the goods plus any incidental or consequential damages. U.C.C. § 2-712, F.S.A. .§ 672.712. These statutory rules vitiate any theory that the subsequent ILA boycott somehow relieved Kaiser of the responsibility for breach. At the moment of breach, FILMO was entitled to suspend performance of the contract and cover. This is exactly what it did; at that moment (prior to the boycott) FILMO’s damages for covering were fixed, and only these damages were sought by FILMO in this suit. FILMO’s cover unquestionably was the result of Kaiser’s anticipatory repudiation; Kaiser, in fact, does not argue otherwise. The damages arising from that cover, therefore, were also the proximate result of Kaiser’s breach, and the subsequent ILA boycott was legally irrelevant to those damages. 6
The cases cited by Kaiser to support its argument are inapposite. In
Manganaro Bros., Inc. v. Gevyn Construction Corp.,
Although the opinion closed with the statement that “Supervening impossibility of performance not occasioned by the defendant puts an end to recovery, regardless of defendant’s prior breach,” the case did not involve impossibility but rather whether the general contractor had committed breach by terminating the contract. The case before us, moreover, does not address whether subsequent impossibility might limit recovery for damages caused by that impossibility.

Here Kaiser’s cancellation, not the subsequent ILA boycott, caused FILMO to cover; consequently the boycott

Kaiser also complains that the trial court erred by submitting to the jury the issues of whether a contract existed between Kaiser and FILMO and if so its exact terms. Kaiser asserts that the contract was unambiguous and should have been construed by the trial court as a matter of law. Kaiser further contends that after construing the contract, the court should have directed a verdict in its favor.
We disagree. The primary dispute between FILMO and Kaiser was whether the shipment term meant that FILMO had to provide a vessel
at the port
by December 31 or whether it had to provide a vessel which
could be loaded
by December 31. Although the interpretation of a contract is for the court when the contract is unambiguous,

Kaiser’s final claims relate to two eviden-tiary matters. Kaiser first asserts that the trial court abused its discretion in not permitting an expert witness who was not disclosed on the pretrial witness list to testify at trial. Kaiser claims it was severely prejudiced by the exclusion of this witness and that FILMO was not prejudiced by the failure to disclose the witness prior to trial; hence the trial court should have permitted the expert to testify.
Whether to exclude a witness not listed in the pretrial witness list is discretionary with the trial court, and the decision is reviewable only for abuse. Newman.
v. A. E. Staley Manufacturing Co.,
Applying these factors to the case before us, we conclude that no abuse of discretion occurred. Although the witness, Michael vanGelder, would have testified on the admittedly crucial issue of the commercial meaning of the contract’s “shipment” term, Kaiser did present the testimony of two witnesses on this issue. More important, however, is the apparent lack of good faith by Kaiser in producing this witness and the absence of any credible explanation for not making prior disclosure. In the pretrial witness list filed by the parties on January 23, 1981, Kaiser listed a Jack Berg as an expert witness, but not vanGelder. Prior to this time Kaiser had failed to indicate in its answers to FILMO’s interrogatories that it intended to call any experts, and Berg was disclosed only after discovery had ended. On January 26, the court ordered
Kaiser’s final complaint is that the trial court erred in permitting FILMO to introduce evidence of the load capacity of the UELEN while prohibiting Kaiser from showing why the UELEN was not loaded. The load capacity of the UELEN, however, was highly relevant to FILMO’s damages. FILMO sought damages for 8400 metric tons of cover pursuant to a provision in the contract that permitted FILMO to request an additional 5% of the contract amount; the evidence of the load capacity of the UELEN was essential to show that FILMO was entitled to invoke the 5% option under the contract and hence was entitled to damages for the 8400 metric tons of DAP actually purchased and delivered. In contrast, as we have held above, the reasons why the UELEN was not loaded were irrelevant to this lawsuit. Questions of relevancy of evidence are discretionary with the trial court,
United States v. Dothard,
AFFIRMED.
Notes
. This telex stated: “Would you please ensure that material is moved during December otherwise order will have to be cancelled, which would l e a pity.”
. After cancelling Kaiser resold the DAP ex-warehouse to Cargill, Inc., at a price substantially higher than that in the FILMO contract. FILMO had previously offered to purchase the DAP ex-warehouse so that Kaiser could report the profit on the sale in 1979, but Kaiser re-jeced this offer.
. The parties agree that the substantive law of Florida governs this lawsuit.
. Kaiser apparently chose this strategy to avoid the application of U.C.C. § 2-614(1), F.S.A. § 672.1-614(1) which states:
Where without fault of either party the agreed berthing, loading, or unloading facilities fail or an agreed type of carrier becomes unavailable or the agreed manner of delivery otherwise becomes commercially impracticable but a commercially reasonable substitute is available, such substitute performance must be tendered and accepted.
Alternate performance was available by shipping the DAP in a non-Soviet vessel, which in fact is what FILMO did.
. Kaiser asserts in its brief that at the time of the motion to strike the court could not know Kaiser would be found liable for breach. While this assertion is correct, it misses the point. Kaiser’s affirmative defense became relevant only if Kaiser was found guilty of breach. The
. This result is consistent with both the language and purpose of the U.C.C. Permitting Kaiser to defend its anticipatory breach by the subsequent actions of the ILA would run contrary to U.C.C. § 2-610’s direction that after an anticipatory repudiation, the aggrieved party “may resort to any remedy for breach” and need not wait until performance was due under the contract. Kaiser’s interpretation, moreover, would go far toward destroying the certainty in commercial transactions this section was designed to achieve by permitting the aggrieved party to immediately exercise his rights on breach.
. Had FILMO sought compensatory damages for a delay in shipment resulting from the ILA boycott rather than for cover, for example, Kaiser’s “impossibility” defense might well have been relevant.
. Kaiser has not challenged this ruling on appeal.
