BALTIMORE -- Shota Imanaga had one more gem to piece together for the Cubs before heading into his All-Star break. In putting the finishing touches on a brilliant first-half, the lefty handled one of baseball’s best lineups in Baltimore and hung with a Cy Young Award winner in Corbin Burnes.

Next up for Imanaga is the national stage.

On Wednesday night, the Cubs’ standout rookie guided his team to a 4-0 victory over the Orioles at Camden Yards with six scoreless innings. That helped Chicago pick up consecutive series wins for the first time since April 12-17, and gave the North Siders their first three-game win streak since April 23-26.

“The days that I start, I'm going out there to win, help the team win,” Imanaga said via his interpreter, Edwin Stanberry. “But that's only one win for one outing. It's not five or 10. So I think what's important [for our team] is to focus on each day and just get the wins, stacking up the wins and then don't think too far in the future.”

Imanaga was a big part of the Cubs’ solid start to the season in April -- winning the National League’s Rookie of the Month honor -- and he will continue to be integral in the club’s efforts in pulling back into the Wild Card picture. The Cubs have gone 13-4 on days Imanaga has pitched, and 31-45 in the remaining games.

Through 17 starts, Imanaga is now 8-2 with a 2.97 ERA and 98 strikeouts against 16 walks in 97 innings. Dating back to 1933, when the first MLB All-Star Game was played, Imanaga is one of three Cubs pitchers with at least 97 innings and no more than 16 walks before the All-Star break, joining Jon Lieber (2002) and Dennis Eckersley (1985).

“He's humble. He's a nice guy. He's funny,” Cubs catcher Miguel Amaya said of Imanaga. “But when it's business time, he's out there doing his job. That's why he's an All-Star for us.”

Against the Orioles, Imanaga scattered six hits, racked up six strikeouts and ended with one walk in his 11th quality start of the season. On the other side, Burnes also delivered a quality start, but yielded three runs. Christopher Morel got the Cubs’ offense going in the second inning with a solo shot to center -- his 16th blast of the year.

The pitcher-friendly dimensions in left field also helped Imanaga’s cause. Austin Hays and Adley Rutschman each flew out to the warning track. In the sixth, Jordan Westburg doubled off the wall on a shot that would have been a homer in the 29 other ballparks, per Statcast. The Cubs starter struck out the next two batters to strand a pair to close out his start.

After Westburg’s near homer, the Orioles had two runners aboard with one out and the Cubs clinging to a 3-0 lead. Imanaga worked the next batter, Ryan Mountcastle, into a 2-2 count and finished him off with a four-seamer low in the zone for a called third strike. The lefty then put Jorge Mateo behind, 0-2, and got him to chase a splitter that faded low and away and out of the zone.

“The sixth inning was great,” Cubs manager Craig Counsell said. “With second and third there, a chance to do it again and he just just bore down. Two great at-bats. Two strikeouts. That was a heck of a way to finish and a heck of a start.”

Imanaga even garnered praise from Orioles manager Brandon Hyde.

“Give Imanaga credit. I thought he was excellent,” Hyde said. “Three balls were really barreled up -- two flew out to the wall and one went off the wall. We didn't do a ton besides that. I was really impressed.”

Imanaga closed out his first half with back-to-back outings opposite Zack Wheeler of the Phillies and Burnes. Not only was he facing lineups filled with All-Stars from Philadelphia and Baltimore, but the Cubs lefty was being tested against two of baseball’s best arms. Imanaga enjoyed that aspect of his starts ahead of the Midsummer Classic.

“They’re two amazing pitchers,” Imanaga said. “When I’m facing them, there’s a lot I can learn from them, so I used it as an opportunity.”

Imanaga also sees the All-Star Game as a chance to pick the brains of some of his peers. He named Phillies lefty Ranger Suárez and Dodgers righty Tyler Glasnow as two pitchers, in particular, who he would like to find time to discuss pitching.

Imanaga was also very much looking forward to possibly pitching in the All-Star Game.

“If I get the opportunity to pitch, I would like to,” Imanaga said.
