Berenguer had a high nineties fastball which earned him the nickname "el gasolino" & "senor smoke". He also was known as "pancho villa" with his menacing looks of long hair & moustache on the mound.
He put up big strike out numbers in the Mets minors going from A ball Lynchburg to AA Jackson & then AAA Tidewater in three quick seasons. Unfortunately he was having major control issues & was walking almost as many batters as he struck out. By 1978 he was 10-7 with a 3.67 ERA & 130 Ks at Tidewater when he got the big league call up to a Mets team looking for something.
He debuted on August 17th, getting his first start, but gave up five runs on four hits to the San Diego Padres earning a loss. He returned as a September call up taking another loss on September 4th, as the Pirates roughed him up for five more runs at Pittsburgh. He ended the year at 0-2 with an 8.31 ERA.
He got another September call up appearing in five games going 1-1 with a solid 2.93 ERA. In his last start on September 29th he pitched 7.1 innings beating the St. Louis Cardinals 6-2 for his first career win. In 1980 another September call up resulted in a 0-1 record, with a 5.79 ERA in six games. In his three seasons with the Mets he struck out 40 batters but walked 33 in 53 innings of work. The Mets did not like his control issues & traded him to the Kansas City Royals for Marvell Wynne.
Trivia: He appears on two different Mets Rookie Prospects cards- 1979 & 1981. The 1981 card features Mets future hero; Mookie Wilson.
