Appellate Procedure 81(b)(1), the burden of establishing reversible error is on the complaining party. Nix v. H.R. Management Co., 733 S.W.2d 573, 575 (Tex.App. — San Antonio 1987, writ ref'd n.r.e.), citing Lorusso v. Members Mutual Insurance Co., 603 S.W.2d 818, 821 (Tex.1980). The complaining party must show that the trial was materially unfair. Id. If appellants wish to complain of harm resulting from the admission of evidence, they must present the entire statement of facts to make such a showing; otherwise, the entire burden of proof on appeal would shift to appellees. Cf. Rowlett, 741 S.W.2d at 208. The record, as it was brought before us, does not afford a substantial basis for the reasonable belief that such evidence caused the rendition of an improper judgment. TEX.R.APP.P. 81(b)(1). Applying the presumption of rule 53(d) that “nothing omitted from the record is relevant ...,” we conclude that appellants have failed in their burden to show harm. Accordingly, we overrule appellants’ first point of error.
In their second point of error, appellants argue that the trial court committed reversible error by prohibiting appellants’ rebuttal witness, Richard Turner, from fully testifying about the results of scientific, demonstrable tests and his conclusions regarding the coefficient of friction and surface conditions of the Gulf station. Following Gulf’s case-in-chief, appellants offered Turner to rebut testimony of George Tier, a designated expert presented by Gulf, regarding the coefficient of friction for the service station, the slickness of the surface, the general safety to the motoring public, and the existence of Gulf’s safety manuals for the operation of service stations. Gulf and TMM objected to Turner’s testifying because he had not been identified by appellants in response to interrogatories which requested that appellants provide the names of expert witnesses and the subject matter on which the experts were expected to testify. Gulf argued that Turner was never designated, and Gulf first learned at trial that appellants intended to call him as a rebuttal witness. The court permitted
Turner to testify but restricted Turner’s testimony, disallowing him to testify about tests showing the coefficient of friction for the service station in question and the adjacent driveway entrance, the effect of a mixture of water and gasoline on the surface and the safety to the motoring public. The trial court reasoned that these subject matters were not a surprise to appellants and, therefore, did not necessitate calling a rebuttal witness. Turner was permitted to testify at length about the surface, including photographs. Appellants argue that their surprise at the testimony of one of Gulf’s experts necessitated their calling Turner in rebuttal. TMM and Gulf argue that Turner was called merely in a desperate effort to correct appellants’ own expert’s inadequate preparation as to tests which had been previously disallowed by the trial court.
Appellants concede that they have the burden of proof of showing good cause for Turner, a previously unidentified expert witness, to testify. At trial, appellants attempted to show good cause by explaining that the subject matter of the witness’s testimony was to rebut the testimony elicited from Tier, Gulf’s expert witness who was designated on the thirtieth day before trial, and to rebut testimony from two other timely designated expert witnesses.
Appellants made no showing of good cause. See E.F. Hutton & Co., Inc. v. Youngblood, 741 S.W.2d 363, 364 (Tex.1987). The trial court properly exercised its discretion in limiting Turner’s testimony to subject matters within the realm of proper rebuttal as appellants made no showing of good cause. Furthermore, even if the trial court’s ruling constitutes an abuse of discretion, we can find no harmful error upon review of the partial statement of facts. We overrule appellants’ second point of error. Consequently, we affirm the trial court’s judgment.
