Already taxed without injured relievers Jordan Walden and Scott Downs, the Angels haven't received much support from the starters, who are struggling to go deep into games. Additionally, with Downs not available, the bullpen is left with just one left-hander, Hisanori Takahashi.
"This gets back to, really, our starting pitching, as the starting pitchers can pitch to a certain point in the game," manager Mike Scioscia said. "If you look at our last 20-some starts, I think we're only averaging maybe 17 outs. That's a big difference from the projection of what these guys had done earlier, when they were getting routinely 20-22 outs."
"We might go a stretch all next week where we don't even get up to warm up," reliever LaTroy Hawkins said. "It's all part of the job and I think that's part of the joy and the interesting part about being a bullpen guy. The season's got its ups and downs and highs and lows."
White Sox starter Francisco Liriano doesn't have to worry too much about fatigue, with the team going to a six-man rotation, Liriano's next start will come with extra rest.
"I've never done it before so we'll see," Liriano said. "I don't know yet. I'm going to talk to [White Sox pitching coach Don] Cooper and just prepare myself for six days or five days."
Liriano will be making his second start and home debut with the White Sox after a trade brought him over from the Twins. In his first start, he gave up two runs on four hits and struck out eight, but got a no-decision in a matchup against his former team.
Angels: Haren starting after bout with back stiffness
Haren will be making his first start in over a week after skipping his scheduled outing on Wednesday because of stiffness in his upper back, but Scioscia says the veteran is ready to go.
"Dan, since he's come off the disabled list, he's had a couple starts and the second one he just came down with a little bit of an upper back stiffness, different than what hurt him before, but he feels great," Scioscia said before his team evened the series with a 6-5, 10-inning win on Saturday night. "He's rebounded and had a great throwing session and is excited about how he feels physically. We're looking forward to a good start from him tomorrow."
White Sox: Bullpen on a roll
Despite giving up a run in the 10th inning on Saturday, the White Sox bullpen continued its impressive run, with 3 2/3 innings of one-run ball. The bullpen has a 1.06 ERA in its past 12 games.
Alex Rios had a hit on Saturday, but was unable to extend his multi-hit streak to five games. Rios was 9-for-18 during the four-game stretch in which he had two or more hits per contest.
Haren has only faced the White Sox four times during his 10-year career, and is 1-1 with a 4.18 ERA. A.J. Pierzynski has more success against the righty than any of his teammates with a .357 average (5-for-14) and an RBI.
When Liriano and the Angels' Mark Trumbo face off, it's usually all or nothing. In 10 at-bats against Liriano, Trumbo has three hits, two of which are home runs. Conversely, Liriano has struck out Trumbo four times.
