A founding member of the Sea Kittens, and the inspiration behind creation of the team- as in, it was her idea to put together a softball team. She had no idea...

Erin “Mama Cat” O’Brien proposed assembly of a softball team in late winter, 2010, and from that idea Sea Kittens were born. She particularly enjoys the late-night conversations about batting order and defensive alignments that Sea Kittens brought to her marriage. Mama Cat has appeared in 184 of the team’s 203 games to date, posting a career 443/468/536 slash and is the only two Sea Kitten woman to have more than 100 career runs scored. Her career batting average and slugging percentage are tops among Sea Kitten women and reflects her impressive ability to drive the ball: Mama Cat is the only Sea Kitten woman who has hit 4 or more extra-base hits in a season, and she has accomplished the feat four times (Summer 2012, Fall 2013, Fall 2017, and Summer 2018).

She holds the best single – season batting average among Sea Kitten women, posting a 0.643 mark in summer 2022 to top the ).632 mark she established in 2015- before parenting! Taking her game up a level in fall, 2017, O’Brien smashed 9 doubles- tying Mercury Stevens for the team fall-season record- and knocked home 14 runs, the all-time best for a Sea Kitten woman.  Her 35 career doubles are 28 more than the #2 woman on the SK all-time list, and she is tied for #3 overall on the career triples list (7), but she’s still waiting for that first glorious round-tripper.

Mama Cat’s first softball memory is vamping in the batter’s box as a second grader- “Go Pumas!”

Her favorite Sea Kitten memory is Kyle foiling an intentional walk attempt in extra innings to deliver a 15-14 walk-off win against Packer Inn in 2010.

Erin finds SYB’s mouthy pitcher the most annoying thing on the softball diamond.

Post-pandemic, Mama Cat has a 0.573 batting average through 32 games, more than 125 points higher than her pre-pandemic lifetime average.
