Monday’s American League results

Orioles 4, Blue Jays 1, 1st game; Blue Jays 9, Orioles 5, 2nd game — J.P. Arencibia broke open a tight game with a seventh-inning grand slam, and the Toronto Blue Jays beat host Baltimore 9-5 Monday night to earn a doubleheader split and drop the Orioles 1½ games out of first place in the AL East. In the opener, Adam Jones went 4-for-4 with a homer and two RBI to lead Baltimore. The Orioles fell behind 4-0 in the nightcap and missed several bases-loaded chances to take the lead before Arencibia connected off Jake Arrieta to give Toronto a 9-4 cushion. Juan Encarnacion hit his 41st home run for the Blue Jays, who snapped a seven-game skid. Arencibia, who came into the game mired in a 2-for-36 slump, finished with three hits and five RBI. Ricky Romero (9-14) allowed four runs, eight hits, four walks and a homer in five-plus innings. But a strong performance by the Toronto bullpen enabled the left-hander to end a 13-game losing streak over 15 starts since June 22.

Tigers 6, Royals 2 — Justin Verlander breezed through eight innings and Prince Fielder hit a solo homer, helping the host Detroit Tigers steady themselves with a victory over the Kansas City Royals. Detroit entered one game behind the first-place Chicago White Sox in the AL Central after being swept in a doubleheader by Minnesota on Sunday. Verlander (16-8) had little trouble with the Royals, who knocked him around for eight runs and 12 hits last month. The right-hander allowed two runs and nine hits this time, striking out eight without a walk. Jose Valverde pitched the ninth. Luke Hochevar (8-15) yielded six runs — five earned — and 12 hits in 7 1-3 innings. Alex Gordon homered for Kansas City.

Yankees 6, Twins 3 — Andy Pettitte turned in another ageless performance with six scoreless innings and the New York Yankees hit four home runs Monday night to beat host Minnesota and extend their AL East lead. After playing three tense, one-run games against Oakland over the weekend, including their startling comeback for a 14-inning win on Saturday, the Yankees enjoyed an easy one for a change. This was New York’s 10th victory in 12 games.

Monday’s National League results

Nationals 12, Brewers 2 — This time, the “sun monster” helped Jayson Werth’s host Washington Nationals and hurt the Milwaukee Brewers. A day after the Nationals misplayed a pair of fly balls in the midday glare, Werth wound up with a two-out, two-run double when Brewers center fielder Carlos Gomez lost a ball in the sun to spark a six-run fourth inning, and Washington beat Milwaukee to cut its magic number for winning the NL East to five. Jordan Zimmermann (12-8) allowed one run and four hits in 6? innings, while delivering two hits and driving in a run as a batter. Ryan Zimmermann produced three hits and four RBI for the Nationals, who are a majors-best 93-60 and increased their division lead over the Atlanta Braves to five games with nine to play. Marco Estrada (4-7) lasted only four innings for the Brewers, who entered the day 2½ games behind the St. Louis Cardinals for the NL’s second wild-card berth. He allowed seven runs — six earned — and eight hits.

Mets 6, Pirates 2 — Ike Davis connected twice and reached a career-high 30 homers, Jenrry Mejia pitched five effective innings for his first major league win and the host New York Mets beat the plummeting Pittsburgh Pirates for their fourth straight victory. Davis had a career-high five RBI and David Wright had a run-scoring single to move within two hits of tying Ed Kranepool’s franchise record of 1,418 hits. The Pirates lost for the 31st time in 43 games since improving to a season-high 16 games above .500 (63-47) on Aug. 8. They started the day 6½ games back in the wild-card race with several teams ahead of them, and now need to win six of their last nine just to finish at break even.
