Angeles was plagued by numerous mental mistakes that kept him from becoming a regular starter. Despite these issues, however, Guerrero proved a solid contact hitter with an ability to hit for average, posting a .291 average in 1997. However, he did not hit for power, with only 4 home runs, and despite being known as a speedy runner, he only stole 6 bases in 1997 while being caught 5 times. Montreal Expos (1998-2000) Guerrero began the 1998 season with the Dodgers, but was traded at the deadline to the Montreal Expos with minor league first baseman Jonny Tucker, outfield prospect Peter Bergeron, and pitching prospect Ted Lilly for outfield prospect Hiram Bocachica, second baseman Mark Grudzielanek, and starting pitcher Carlos Perez. The deal also united Guerrero with his younger brother Vladimir in Montreal. Despite having fallen out of favor in Los Angeles, Guerrero again became a starting second baseman in Montreal. He played in all 52 of the Expos' final games during 1998, and for the season his combined totals were a .284 batting average, 2 home runs, and 27 RBI. He also stole 8 bases, and was only thrown out twice. On August 15, 1998, he hit his first home run as an Expo in the 8th inning of a game against the Cincinnati Reds. One inning later, his brother homered, making the brothers the 12th pair of siblings to homer in the same game, and only the sixth to do so as teammates. In 1999, Guerrero hit .292, again with 2 home runs, and 31 RBI in 132 games. He stole 7 bases and was caught 6 times. On October 2, he launched his first grand slam in the second inning of a 13-3 rout of the Phillies. Since Vladimir had homered earlier in the game, it was the second time the brothers had homered in the same game. During the 2000 season, Guerrero began seeing more time in the outfield due to the emergence of Jose Vidro. His batting average fell to .267, but he once again hit 2 home runs, this time driving in 23 runs. He stole 8 bases and was caught once. His two home runs, the first May 18 against the Arizona Diamondbacks, and the second September 18 against the Florida Marlins, came in games where Vladimir had already homered, the third and fourth times the brothers had both homered in the same
