Leake had been solid in the Reds' rotation this year, going 9-5 with a 3.56 ERA. He has been even better here in July, as he posted a 1.25 ERA in five starts this month.
The Giants have officially announced the trade. They are sending two minor leaguers, right-hander Keury Meila and first baseman Adam Duvall, to the Reds in exchange for Leake.
Despite the brilliant effort, Nelson was left with a no-decision after the bullpen allowed the Cubs to score five runs over the final two innings in the 5-2 Cubs' win.
Nelson had a strong month of July, going 3-1 with a 1.64 ERA in five starts.
Burnett gave up a first-inning home run and wasn't very effective after that. He threw 97 pitches in his short stint, walking two and striking out four.
Burnett has now lost two straight games, and has seen his ERA rise from 1.99 on July 6 to 3.06.
Arrieta actually left the game trailing 2-0, but the Cubs were able to rally back late in the game to get the right-hander off the hook.
Arrieta was brilliant in his six July starts. He went 4-1 with an impressive 1.90 ERA and a 44:11 K:BB ratio. He has now thrown eight consecutive quality starts.
Holmberg went six innings, allowing just five hits and two runs. He walked three and struck out four, and was the beneficiary of a ton of offensive support.
Holmberg was 2-2 with a 5.08 ERA in eight prior MLB appearances, six of them starts.
Martinez had a 2-1 lead after the second inning. But in the fourth, he gave up three more runs, including a two-run home run by the opposing pitcher Chris Rusin. Martinez allowed another run to score in the fifth before his night was done. He threw 100 pitches (69 strikes) in his five innings of work.
This was Martinez's worst start in quite some time, as it was the first time he had allowed more than three runs since May 9. In five starts this month, Martinez went 2-1 with a 2.03 ERA.
Rusin got off to a shaky start, allowing four runs through the first two innings, including a three-run homer by Matt Carpenter in the second. Carpenter got to Rusin again in the fifth, as he blasted a solo shot as part of a two-run inning.
The young hurler did help his own cause in this one, as he went 2 for 2 at the plate, including his first career home run--a two-run shot in the fourth inning.
The Rockies' southpaw finishes July 0-2 with a 4.50 ERA over six appearances--five starts.
Of the 11 hits--which tied a season-high--all but one went for singles. Domoninc Brown launched a solo home run in the sixth inning for the only extra-base hit against Miller.
But the Phillies scored two in the fourth, and one each in the fifth and sixth innings, en route to the victory.
Miller went 0-4 with a 3.24 ERA in five starts this month.
On Thursday, Harang limited the Braves to one run on nine hits over five innings. He walked one and struck out three, throwing 62 of his 96 pitches for strikes.
Harang (5-11, 3.97 ERA) gave up an early run in the third inning, but the Phillies were able to rally back in the middle innings to secure the victory.
This was a good return for Harang, who had allowed eight runs on 14 hits in his previous start back on July 1. With the win, Harang snapped a personal eight-game losing streak. He had not won a start since May 14.
Cashner allowed an early run in the first inning, but cruised through the next three frames without giving up a run. But he gave up a three-run home run to Curtis Granderson in the fifth before allowing three more runs to cross in the sixth, including a solo blast by Juan Uribe.
Cashner, who has been mentioned in trade rumors recently, was making just his second start since the All-Star break. He is 2-2 with a 3.89 ERA over his past six starts.
