SAN DIEGO (Ticker) -- The San Diego Padres today made a series of roster moves, including purchasing the contract of 21-year-old righthander Buddy Carlyle from Triple-A Las Vegas.

Carlyle will make his first major league start on Sunday when the Padres host the Milwaukee Brewers.

The team also recalled lefthander Heath Murray from Las Vegas and optioned infielder Ed Giovanola and rookie righthander Stan Spencer to the Stars.

Carlyle was 11-8 with a 4.89 ERA in 25 games -- 20 starts -- during his first season at Class AAA. In 160 innings, he allowed 180 hits, including 25 homers, while walking 42 and striking out 138.

Acquired from Cincinnati last April for pitcher Marc Kroon, Carlyle was 30-16 with a 3.33 in his first three professional seasons before this year.

Murray went 0-3 with a 5.31 ERA in 15 games -- seven starts -- with the Padres before being demoted over a month ago. In 15 games -- 11 starts -- for Las Vegas, he went 5-4 with a 4.59 ERA.

Spencer has had an abysmal rookie season, going 0-7 with a 9.16 ERA in nine games. He was given another chance at joining the rotation eight days ago, but since has allowed 13 runs and 14 hits over 5 2/3 innings in dropping a pair of starts.

Giovanola, who pitched 1 1/3 scoreless innings of relief in a 15-1 loss to Philadelphia on Wednesday, is hitting just .190 (10-for-56) with three RBI in 56 games this season.
