Montero hit .224 with 10 homers and 37 RBIs for the D-backs in 84 games last season, and he was 7-for-20 (.350) with seven RBIs and three home runs as a pinch-hitter, tying the franchise record for pinch-hit home runs shared by Tony Clark ('05 and '07), Greg Colbrunn ('01) and Alex Cintron ('05).In other health news, left-handed specialist Doug Slaten threw the equivalent of two innings in a Minor League game in Tucson, Ariz. He threw 23 pitches and did very well, according to Melvin. "Potentially, depending on how he comes through it, maybe the next time out could be in a game," Melvin said. "I would say there's an excellent chance [he'll start the season with us]. If his next time out he's able to get in a game, there should be a good chance." The other primary question regarding the 25-man roster is Randy Johnson's readiness to join the rotation after working his way back from back surgery. Johnson threw on flat ground on Wednesday and is on track for his third Cactus League start on Friday in Tucson against the Dodgers. "It just depends on how we get there and whether or not we feel like he can plug in there sooner than later," Melvin said of the prognosis for Johnson being in the rotation to start the season. "We'll consider all the variables, but with him, we'll err on the side of caution. The last week of spring we'll see where we're at."
