In 2016, the Mets pitchers were falling by the wayside. The team was already in a precarious position in terms of the Wild Card race, and they desperately needed an arm or two to step up and help the Mets stay afloat. One of those arms was Robert Gsellman.

Starting with this debut, Gsellman would go 4-2 with a 2.42 ERA in seven starts and one relief appearance that season. One interesting tidbit about that season was he was dealing with a torn labrum in his non-pitching shoulder limiting him to bunt attempts. Despite, that in his last start of the season, he would actually get his first Major League hit.

When Gsellman made his Mets debut, the Mets were 4.5 games behind the St. Louis Cardinals for the second Wild Card. After that first relief appearance, the Mets were 3.5 games back. When Gsellman picked up his third win of the season, the Mets had a one game lead over the San Francisco Giants for the top Wild Card spot, and that’s where the Mets would be in his final start of the year.

Many expected Gsellman’s career to take off from that point, but that didn’t quite happen. In front of a poor Mets defense, the sinkerball pitcher would struggle in 2017 as a starter leading to the team moving him into the bullpen. In the bullpen, Gsellman has had some great stretches.

Gsellman opened the 2018 season as a reliever, and he was great at the start. Over the first month of the season, he was 3-0 with a 1.80 ERA. He’d struggle to handle the workload not just of a reliever, but also Mickey Callaway going to the whip with him. Gsellman would rebound to have a strong August before tiring the rest of the way.

Again, Gsellman got out to a good start in 2019. Looking over his splits, he was good in every month he pitched but June. While he rebounded in July, he began to strain under the workload, and he missed the rest of the season with a triceps injury. Despite having the injury, Gsellman did all he could do to try to get back on the mound to have the same impact in 2019 as he did in 2016. Unfortunately, he could not make it back.

Through it all, Gsellman has proven himself to be a Major League caliber reliever, and someone who could still yet make an impact in the rotation again. He helped push the Mets into the 2016 postseason. Overall, he has established himself as the best Mets player to ever wear the number 65.
