Here are five things to watch and predictions as the Mets and Pirates play a three-game series in Pittsburgh starting on Friday at 6:40 p.m.
5 things to watch
Mark Vientos' return
The Mets will get a jolt to the lineup on Friday night when Vientos is activated from the IL.
Vientos last played on June 2, and New York's lineup without him and Jesse Winker (who is starting a rehab assignment on Sunday) has been very top-heavy.
While Vientos wasn't running on all cylinders at the time of his injury, he had been hitting the ball relatively well over the prior six weeks.
From April 17 through June 2, Vientos slashed .272/.321/.464 with six home runs and a .785 OPS.
What will be interesting to see is whether the Mets use Vientos at third base (where his defense has left a lot to be desired this season) or slot him in as the regular designated hitter.
Pete Alonso is heating up
After a brief cold snap, Alonso's bat came alive during the final three games against the Braves this week at Citi Field.
He had hits and runs scored on Tuesday and Wednesday, and was in the middle of everything on Thursday as he went 3-for-4 with a double (his 23 doubles this season lead the National League), RBI, and run scored.
Alonso has been in a serious power drought, though, with just one home run since June 8.
With 18 home runs this season and 244 for his career, Alonso is nine homers away from passing Darryl Strawberry for the Mets' all-time record.
Can Paul Blackburn be effective?
With Griffin Canning's season potentially over due to what the team believes is an Achilles injury, it seems Blackburn will be staying in the rotation a bit longer.
As the Mets await the returns of Sean Manaea (possibly in about 10 days) and Kodai Senga (around the All-Star break), it's likely that Blackburn and Blade Tidwell will be asked to help bridge the gap.
It has not been smooth sailing for Blackburn in his two starts since returning to the rotation, as he has failed to provide length while putting the team in early holes.
He allowed three runs in 3.2 innings against the Braves on June 18, and three runs in 4.2 innings against Atlanta on June 23.
No Paul Skenes
Since Skenes pitched on Wednesday against the Brewers, he is not lined up to face the Mets during this series.
Instead, the Mets will face Mitch Keller (4.02 ERA), Mike Burrows (4.45 ERA), and Bailey Falter (3.59 ERA).
Keller was terrific against the Mets during his start at Citi Field on May 13, firing seven innings of two-run ball while giving up five hits, walking one, and striking out eight in what was a 2-1 win for New York.
Falter's start against New York earlier this season was a short one, with him holding them scoreless but allowing three hits and walking five in just 3.2 innings.
The Pirates' offense has been putrid
Pittsburgh has scored 267 runs this season -- the lowest total in the NL and the second-lowest in baseball, ahead of only the Royals (263).
Their most dangerous hitter is Oneil Cruz, who enters this series with a .715 OPS.
Former Met Tommy Pham is struggling badly (.575 OPS), and Bryan Reynolds (.675 OPS) and Ke'Bryan Hayes have not done much (.567 OPS).
As he winds down his career, former MVP Andrew McCutchen is having a solid season, with eight homers and a .744 OPS.
Predictions
Who will the MVP of the series be?
Lindor has been hitting ropes into hard luck for a few days. It's bound to change.
Which Mets pitcher will have the best start?
David Peterson
Expect Peterson to bounce back from his last start, when things spiraled on him against the Phillies in Philadelphia.
Which Pirates player will be a thorn in the Mets' side?
Bryan Reynolds
Reynolds has been hot, with eight hits in his last 17 at-bats.
