Cardinals: 5 numbers that matter after the first week of the season
By Matt Graves

Nolan Arenado already has a 0.8 fWAR
Through the first week of the season, there hasn’t been a hotter hitter in the National League than Nolan Arenado.
Starting on Opening Day with a homer, Arenado is currently second in the MLB with his 0.8 fWAR through just one week. Easily the team’s hottest hitter, Arenado sits with four homers, a 332 wRC+, 1.587 OPS, and is only one of four players in the MLB with double-digit RBI. Arenado won the first week’s NL Player of the Week in part because of a three-double performance last week and this was the first time he’s won the award with the Cardinals.
Coming into the year Arenado spoke about how “upset” he was with his 30+ homer, 100+ RBI season last year (which was objectively his worst full season in a while). With Arenado’s competitiveness and expectations, we should’ve known this was going to happen.
While Arenado won’t finish the year with a 20 fWAR (his current pace), it’s just one way to see just how hot he has been.
