The Giants are interested in Indians closer Chris Perez, Ken Rosenthal and Jon Paul Morosi of FOX Sports report. The Indians, 47-48 after losing four consecutive games, are not planning a massive overhaul in the next week, since they intend to contend in 2013. Yet the Indians constantly gauge trade interest in their roster and could move established players strategically before the end of the month.

If the Indians trade Major Leaguers such as Perez and Shin-Soo Choo, they’d look to obtain players who could strengthen their current team, Rosenthal and Morosi report. GM Chris Antonetti has been monitoring the trade market for a starting pitcher and a right-handed bat.

Perez, 27, has a 3.06 ERA with 10.4 K/9, 1.8 BB/9 and 26 saves so far this year. The right-hander earns $4.5MM in 2012 and can expect a raise to $7MM or so after the season, when he's arbitration eligible for the third time. Perez, a super two player, will remain under team control through 2014.

Giants relievers have combined for a 3.41 ERA with 7.8 K/9 and 3.2 BB/9 so far this year. However, closer Brian Wilson will miss the remainder of the season after undergoing Tommy John surgery and Guillermo Mota is on the restricted list following a 100-game suspension.
