Have you ever played fantasy baseball and decided to punt on closers?

Well the Mets saw their roster at the beginning of the season and decided to do that with left-handed relievers.

Presently on New York’s 40-man roster, the lefties are David Peterson, Chasen Shreve, Joely Rodriguez, Joey Lucchesi, and Locke St. John. Peterson is a starter, Lucchesi is on the 60-day injured list, and St. John has made eight appearances in the majors.

But the two to focus on are Shreve and Rodriguez, and their inability to get batters out.

Shreve, now in his second stint with the Mets, excelled in April. He appeared in eight games, threw nine innings, and allowed two runs while striking out 14 batters. Since he’s thrown in 15 games, 16 2/3 innings, allowed 14 runs and struck out 14.

Shreve was blasted by the Astros in the fifth inning of Tuesday’s game. In his one inning, he walked three batters and allowed three hits. By the time he recorded three outs, the Astros lead went from 3-0 to 7-0.

“I felt like today was the first day that I didn’t pitch well,” Shreve said. “I couldn’t locate my fastball, my splitter was fine. They’re a good hitting team and I didn’t have it today.”

Shreve credited his inconsistency to his splitter. One of three pitches he throws along with a fastball and slider.

“My splitter’s been very inconsistent,” Shreve said. “Sometimes it will be great. In the same outing, some will be great and some will be terrible. It’s been good for me, so I’ve been using (my slider) more.”

Shreve isn’t alone in his struggles. The Mets did a one-for-one swap with the Yankees for Rodriguez, trading right-handed reliever Miguel Castro to the Bronx.

In 27 appearances, Rodriguez has a 5.06 ERA. Left-handed batters are hitting .250/.362/.325 while righties are worse at .205/.326/.608.

Although between Rodriguez and Castro there’s no winner of the trade. Castro has struggled to a 4.35 ERA and lefties are hitting .259/.310/.406. He’s been wild with 11 walks to 20 strikeouts.

With the Mets duo’s struggles, there’s also a question of why they didn’t re-sign Aaron Loup. Loup had a 0.95 ERA in 56 2/3 innings last season. It was one of the greatest seasons by a reliever in Mets history.

Now in Los Angeles, Loup is proving how volatile relievers are. He’s allowed more than double the number of runs as last season in less than half the innings.

What are the Mets options?

Expected to be available through trade are lefties Brock Burke and Matt Moore of the Rangers, the Tigers Andrew Chafin and Gregory Soto, and the Royals Amir Garrett.

The Mets could correct their mistake of not signing Chafin by trading for him but the idea of trading a prospect or player for someone you could’ve signed over the winter isn’t great.

If Jacob deGrom and Max Scherzer are healthy down the stretch, maybe the Mets consider putting Peterson into a relief role.

Within the organization, there are no options to help the Mets immediately. A trade will have to be made to solidify the bullpen.
