Daily Notes for Monday: Masterson, Shields square off

Interleague play is over, and for simplicity's sake, it's convenient to have the DH remain with one set of teams.

The Red Sox's top pitching prospect, Justin Masterson, makes his eighth career start, facing off against James Shields, who has something to prove after lasting just an inning in his previous start against the Red Sox.

Start 'em, sit 'em

Hitters: Jose Guillen is a streaky hitter and in June he has hit .353 with seven home runs. But he also has gone hitless in four consecutive games and is battling a nagging hip injury, which has relegated him to DH duty. Now is a convenient time to send Guillen to your bench indefinitely. … Nick Swisher now has five home runs in June and is hitting .302 with 18 RBIs. That should become the norm for him from here on out, yet Swisher is still available in more than a third of leagues.

Pitchers: Roy Oswalt has allowed just two home runs in 33 1/3 innings in June, compared to nine in 40 innings in May. With 30 strikeouts in June as well, Oswalt clearly pitched better than his ERA and WHIP indicate. He's becoming a safe mixed-league start once again. … Gavin Floyd's past three starts are displaying large red flags for this start. He allowed four runs to the Rockies (at home), including four home runs to a slumping offense. He then allowed one earned run but six unearned runs versus the Pirates. And finally, he allowed four runs to the Dodgers in his most recent outing. The Indians have a pretty suspect offense, but so do the Rockies and Dodgers.

Waiver-wire pickups

Hitters: Jason Kubel is officially hot: He has hits in 11 of his past 12 games, including four home runs, and a 9-to-13 strikeout-to-walk ratio reverses the trends he had in April (three walks, 20 strikeouts) and May (seven walks, 14 strikeouts).

Pitchers: A decent innings-eater facing a weak offense is a bread-and-butter, spot-start chance for fantasy owners, and Kyle Lohse fits the bill in his start against the Mets. The return of Albert Pujols also gives the Cardinals a legitimately strong offense again, which gives Lohse a good shot to earn his 10th win. … Dave Bush is sporting a 2.14 ERA in his past three starts, with a 10-to-3 strikeout-to-walk ratio, and the Diamondbacks, who have the majors' lowest OPS in June at .636, are an easy target right now. Toss in run support (the Brewers rank fifth in OPS in June) and spot-starting Bush on Monday has a large payoff. … Jon Garland is coming off consecutive quality starts against poor offenses, and he gets a shot to make it three in a row versus the A's. Garland's ability to pitch six and seven innings a start makes him particularly well-suited to spot-start duty, because he'll stay around long enough to net the decision when he pitches well.

Weather concerns

Only three games have notable weather issues, with the Royals-Orioles, Pirates-Reds and Nationals-Marlins games all having a 30 percent chance of rain. Red Sox-Rays, Dodgers-Astros, Tigers-Twins, Brewers-Diamondbacks and Blue Jays-Mariners are the weatherproof games of the day.
