The San Francisco Giants have won the first two games of their interleague series with the Cleveland Indians each by one run. So they'll be going for the hard-earned sweep when the teams finish up their three-game set Sunday night at AT&T Park (8:05 pm Eastern, ESPN).

The Giants won this series opener Friday night 4-3, then got a run on a balk in the seventh inning to beat the Tribe Saturday 1-0.

Despite the win San Francisco has been held to two or fewer runs in seven of its last nine games.

So San Fran, at 43-34 and winners of four in a row, lead the NL West by a half-game over the second-place Arizona Diamondbacks.

The Indians, at 40-35 but losers of four of their last five, are now tied for the lead in the AL Central with Detroit.

Cleveland will send Fausto Carmona (4-9, 5.98) to the hill Sunday night against Madison Bumgarner (3-9, 4.06) for San Francisco.

In his most recent outing Carmona got clipped for seven earned runs in 4 2/3 innings of an 8-7 loss to Colorado Monday night. And over his last three starts he's allowed 15 earned runs and four home runs in just 13 2/3 innings of work. On the season the Indians are 6-10 in Carmona's starts, with the over/unders going 10-6.

Bumgarner had been pitching in bad luck most of this year, with just three victories to his credit thanks largely to lousy run support, but his last time out was a disaster, allowing eight straight hits to start the game in losing 9-2 to Minnesota Tuesday night. However, in his three starts previous to that the lefthander had given up just four ER on 20 hits in 20 IP. San Fran is 4-11 in Bumgarner's starts this year, while the totals have gone 6-9.

Being that these two teams last meet three seasons ago neither Carmona nor Bumgarner have started against the lineups they'll face Sunday.

As of Sunday morning is listing the Giants as -138 favorites for Sunday night's game, with an over/under of seven. The Indians are getting +128 as underdogs.

The Giants are 23-13 at home this season, while the Indians are 16-21 on the road.

San Fran has managed to go 16-13 since losing C Buster Posey to that awful leg injury, but they're averaging just 3.2 RPG over that span.

The over/unders are 36-35 in Indians games this season, 28-44 in Giants games, and 11-23 in games played at AT&T Park, which are averaging just 5.9 RPG, easily the lowest among all Major League ballparks.
