CLEARWATER, Fla. — Pedro Martinez's first minor league rehab start in preparation for a comeback with the Philadelphia Phillies was cut short by rain Sunday.

The 37-year-old right-hander worked 1 1-3 innings for the Class A Clearwater Threshers before the Florida State League game against the St. Lucie Mets was stopped because of a downpour.

Martinez, who signed a $1 million, one-year contract this month after sitting out the first half of the season, hit a batter and allowed one hit during a 20-pitch first inning that was delayed more than 30 minutes by an early afternoon storm.

It was raining again by the time he took the mound for the second inning. After retiring the leadoff batter on a first-pitch fly ball, the three-time Cy Young Award winner threw three more pitches before play was stopped.
