NEW YORK (AP) - Right-hander Miguel Batista has been designated for assignment by the New York Mets, possibly clearing a path for top prospect Matt Harvey to make his major league debut Thursday in Arizona.

The Mets recalled righty Elvin Ramirez on Sunday before playing the Los Angeles Dodgers to help a bullpen that has pitched six innings in each of the last two games.

Mets Manager Terry Collins says he hopes Batista clears waivers and agrees to pitch in the minors.

The 41-year-old Batista gave up four runs and five hits while making a spot start for Dillon Gee on Saturday. Gee had surgery to repair an artery.

With Johan Santana on the 15-day disabled list because of an injured ankle and Mike Pelfrey out for the season, the Mets are short on options for their rotation.

Rookie Jeremy Hefner will start Wednesday against Washington but Terry Collins would not say who will start Thursday.

"We're talking about all the options out there," Collins said.

While Collins said Harvey was a possibility for Thursday, the Mets have been reluctant to rush the 23 year old to the majors. The right-hander gave up six runs and seven hits in five innings for Triple-A Buffalo on Saturday.

"Last night was one of those situations when Wally thought his mind was in New York, not necessarily in Buffalo, which I understand," Collins said of Buffalo manager Wally Backman's opinion of Harvey's outing.

The seventh overall pick in 2010 is 7-5 with a 3.68 ERA for Buffalo. He would be on regular rest if he pitched Thursday.

Another possibility to make Thursday's start is 25-year-old Collin McHugh. The righty is 1-3 with a 4.54 ERA for Buffalo. He was 5-5 with a 2.41 ERA for Double-A Binghamton before his promotion.

Batista was 1-3 with a 4.82 ERA for the Mets, including five starts over 30 appearances this year. The journeyman has played for 10 teams and is 102-115 with a 4.49 ERA in 18 big league seasons.

"Miguel's done a great job here," Collins said. "He brings a lot to the party as far as his clubhouse presence ... and he's a good job. Whenever you call his name he pitches.
