Based solely on the 1-player modes (there are 2 single-player modes, one where you play as the home team and one where you play as the away team). I won 2 games against the CPU: 26-13 as the home team and 41-1 as the away team. In also had an aborted game where I was winning 10-0 when the CPU decided to throw the ball around after an out and not catch it. It came to rest about 1/3 of the way down the 3rd base line and none of their players went to pick it up. The game won't advance until the pitcher has the ball while on the mound.
While I believe Super Baseball was Atari's 3rd attempt at a baseball game on the system and the follow up to this game, this one is very slightly better. Reading through the manual made me think the programmer(s) had no clue about the sport. While the fielders aren't so fast that the left fielder can field a grounder and beat the batter to first base, like in Super Baseball, they can all gun down the batter at first base on any batted ball that's not a HR. So, as long as you are able to cleanly field any batted ball, you'll never give up any hits. While you have three pitches at your disposal, in addition to throwing an intentional ball, I couldn't tell any difference between them. It really doesn't matter against the CPU anyway, as it'll hit any pitch in the strike zone and take the intentional ball. When batting, you might as well swing at every pitch, since if you have the timing down as to when to swing and press down while you swing, probably 95% of the time you make contact (I'm assuming the times you don't are when the CPU throws an intentional ball), you'll hit a HR. Just like my time with Super Baseball, every single hit I got was a HR. Also just like in Super Baseball, you play the bottom of the 9th, even if the home team is ahead. Another minus is that you always have to tell the runner(s) to advance, even having to tell the batter to start running after making contact -- yes, he will just stand in the batter's box if you don't. It doesn't even automatically advance the runner(s) around the bases when you hit a HR, as you have to tell them to advance every time they reach the next base (I'm assuming you have to do it when there are runners on base, as I never encountered that situation).
For some reason, after getting an out or giving up a HR, the CPU would throw the ball around the field before the next batter would step up to the plate -- and the batter won't do that until the pitcher has the ball on the mound. At least half of the time after I hit a HR, the catcher would throw the new ball to the pitcher who was running towards home plate, then the pitcher would throw to 1B, about half of the time missing the first baseman, causing him to have to chase down the ball in RF, then the 1B would throw it back to the P and miss, causing the P to chase it down in LF. The P would then run back into the infield, pause for a few seconds, throw it to the C, who would wait another few seconds before throwing it back to the P, who was back on the mound. After all this, my next batter would finally head up to bat. I wouldn't be surprised if that sequence took up at least 10% of my playtime.
