LEADING OFF: Cubs check Darvish, ace matchup in Philly

A look at what's happening around baseball today:

CHECK HIM

The Chicago Cubs might have further word on Yu Darvish after the Japanese ace said he felt soreness in his troubled triceps tendon following a minor league rehab start. Darvish hasn't pitched in the majors since May 20 because of right triceps tendinitis. He threw five sharp innings for Class A South Bend on Monday, and was set to rejoin the Cubs during their series at Dodger Stadium.

''In the triceps there's likeliness to get more fatigue there, especially if there's a long gap between innings,'' he said through a translator. ''That's when I feel fatigue there. Not necessarily pain, but I can't for sure say there is nothing going on in the tricep zone.''

NIMMO NEEDED

The Mets take a seven-game skid into their game against Pittsburgh, but at least they may get their most productive hitter back. Brandon Nimmo has a sore right pinkie after getting hit by a pitch Sunday, but an MRI showed no broken bones and he is day to day. He didn't start Monday but entered as a pinch-runner in the eighth inning and stayed in the game to play left field. The Mets have also lost 14 of 15 at home and are 13-25 at Citi Field this season.

ACES ALONG I-95

Aces Luis Severino and Jake Arrieta square off as the Yankees continue a series in Philadelphia. Severino (11-2, 2.24) has never faced the Phillies, and Arrieta (5-5, 3.42) is 3-1, 3.83 in seven career starts vs. New York. The Yankees won the series opener Monday in their first appearance at Citizens Bank Park since beating the Phillies in the 2009 World Series. The Yankees improved to 14-14 against the Phillies, leaving the Los Angeles Dodgers as the only team they have a losing record (6-7) against in the regular season.

ON THE SKIDS

Carlos Martinez has lost three straight decisions entering a tough test against Corey Kluber and the Indians. Martinez (3-4, 3.24) hasn't won since May 2, and St. Louis has dropped his past five starts, a span in which he has a 7.06 ERA. Kluber (11-3, 2.10) pitched seven innings of one-hit ball in a 12-0 victory over the White Sox in his previous outing.

COLLEGES

Oregon State and Arkansas begin the College World Series, a day after the opener in their best-of-three matchup was rained out in Omaha. Luke Heimlich (16-2) starts for Oregon State against the Razorbacks' Blaine Knight (13-0).

A two-time Pac-12 pitcher of the year, Heimlich was not picked in this month's Major League Baseball draft. He wasn't with the team at last year's College World Series after it was revealed he had pleaded guilty to molesting a young relative when he was 15. He served two years' probation and went through a treatment program, but later denied wrongdoing in interviews with Sports Illustrated and The New York Times.
