Feldman (6-9, 5.43 ERA): Feldman is expected to make the start after coming off the disabled list with a right knee bone bruise. He left his last appearance for the Rangers (out of the bullpen) with the injury. Feldman was supposed to start Sunday's game for Oklahoma City as part of his rehab assignment, but was scratched when Cliff Lee was pushed back because of a strained back muscle. Feldman allowed two runs on five hits in four innings with three strikeouts and two homers in his only rehab appearance for OKC. He was the Rangers' Opening Day starter after his excellent 2009 season, but he hasn't been able to match that. He was 5-9 with a 5.46 ERA in 20 starts before going to the bullpen in late July. Since then, he's had a 5.06 ERA in five relief appearances before the DL stint. Feldman is 0-1 with a 5.02 ERA in two starts against the Blue Jays this season. He took a no-decision on Opening Day (Rangers won that game on a walk-off single by Jarrod Saltalamacchia) and lost on May 15 in Toronto after allowing five runs in 7 1/3 innings.
Marcum (11-7, 3.53 ERA): After going 1-3 with a 5.06 ERA in August (inflated by one bad outing), Marcum bounced back in his last start, giving up one run on five hits with two walks and seven strikeouts in six innings against the Rays. But he got a no-decision in a 2-1 loss. Marcum has thrown four straight quality starts, including a nine-inning complete game against the A's a few weeks ago. In his lone start against the Rangers this year, Marcum gave up three runs on two hits in seven innings and held the Rangers to just .087 as a team.
Hitters: Three current Rangers have had eight or more at-bats against Marcum: Vladimir Guerrero (5-for-15), Michael Young (4-for-13) and Ian Kinsler (4-for-8). Five Blue Jays have 11 or more at-bats off Feldman: Lyle Overbay (3-for-16), Aaron Hill (3-for-14), Adam Lind (6-for-14), Vernon Wells (5-for-12) and John Buck (2-for-11).
